The Hassenfeld Library on the University School of Nashville campus ranks among the best buildings constructed within the city since 2000. There are so many characteristics of the structure's exterior that I find appealing — include the brick color, the stone touches, the engraved "Hassenfeld Library" (seen in the lower photo along the roof line) and the 12-paned traditional windows.
But two elements stand out: 1. the building's contemporary segment (seen on the left half of Hassenfeld in the photo below) interacts effectively with the otherwise traditional design, thus allowing the admirer to realize that this is a "new building" that pays tribute to a timeless style. My only criticism is that the contemporary piece is a tad too large. 2. The building plays nicely off the other, and older, USN structures (they are not seen in the first photo). Given Hassenfeld, which opened in 2004, physically connects with its stately counterparts, a seamless symbiotic relationship is important.
If anybody knows the architect (I Google searched with no luck), please ID.
